(6) Miscellaneous settings
Cooling-only setting for the indoor unit: Cooling only model (Factory setting: SW3-1 "OFF.")
When using indoor unit as a cooling-only unit, set SW3-1 to ON.
(7) Various types of control using input-output signal connector on the outdoor unit (various connection options)
*4. By setting Dip SW5-5, the Low-noise mode can be switched between the Capacity priority mode and the Low-noise pri-
ority mode.
When SW5-5 is set to ON: The low-noise mode always remains effective.
When SW5-5 is set to OFF: The low noise mode is cancelled when certain outside temperature or pressure criteria are
met, and the unit goes into normal operation (capacity priority mode).
*5. Each outdoor unit in the system with multiple outdoor units requires the signal input/output setting to be made.
*6. Take out signals from the outdoor unit (OC) if multiple outdoor units exist in a single system.
CAUTION
1) Wiring should be covered by insulation tube with supplementary insulation.
2) Use relays or switches with IEC or equivalent standard.
3) The electric strength between accessible parts and control circuit should have 2750V or more.

Performs a low level noise operation of the outdoor unit by an ex-
ternal input to the outdoor unit.
* It can be used as the silent operation device for each refrigerant
system.
Low-noise mode
(level)
*3 *4
*3. Low-noise mode is valid when Dip SW4-4 on the outdoor unit is set to OFF. When DIP SW4-4 is set to ON, 4 levels of
on-DEMAND are possible, using different configurations of low-noise mode input and DEMAND input settings.When 2
or more outdoor units exist in one refrigerant circuit system, 8 levels of on-DEMAND are possible.
Forces the outdoor unit to perform a fan operation by receiving sig-
nals from the snow sensor.
